To all whom it may concern: I attached to a projecting bracket from a post Be it known that I, LUOIO FERREIRA, a citito support the rope, as indicated byjj j" in zen of Portugal, residing at Paauhau, Island Fig. 1. In the construction of the trolleys I of Hawaii, Territory of Hawaii, have inventuse a piece of pipe or tubing 0 free to turn 55 ed certain new and useful Improvements in on the pin it in the yoke 7;, which terminates Aerial Tramways for Conveying Crops or in the hook t at its lower end. At each end Merchandise; and I hereby declare the folof this pipe 0 is secured a disk n a, between lowing to be a full, clear, and exact descripwhich the sheave or wheel 19 is free to re tion of the invention, such as will enable oth- 'volve upon the pipe 0. These disks straddle 6o 10 ers skilled in the art to which it appertains the rope and prevent the trolley from jumpto make and use the same. ing off, and the whole forms a simple and My invention is designed for aerial tramcheap construction.

When such a tramway is for the rope a and grooves t and t on its top used, for example, to convey harvested suand along its diverging edges for the two gar-cane in bundles from the fields to the branch ropes.
